Mysteries of the Sith is tedious to say the least. The game is much more obtuse than Dark Forces and Jedi Knight I ever were, I spent a lot of time wandering around looking for progression that turned out to be a random hole in the ceiling or a grate obscured under a platform. I really would not have beaten the game if not for two things: walkthroughs and cheats.

The game is quite a bit more difficult than the previous one, leaving the player fighting for every scrap of health and shields they can find, spending most of the time with low health and no shields. The beginning and end of the games are the worst parts in my opinion, with the middle levels being quite fun.

Story-wise there is not much to say, most of the story is just random Mara Jade adventures, which is pretty fun. This is the only game that stars Mara, and so it is great to see her personality. Kyle Katarn takes a back seat, only appearing at the beginning and end of the game. It does feel a bit irrelevant to the overall Dark Forces/Jedi Knight story, and you can really tell it is more of an expansion than a full-fledged sequel.

I don't know if I'd recommend playing it. I did not enjoy my time overall, I would say to just watch a compilation of the cutscenes and move on to Jedi Outcast if you are playing through the whole series like I am.
